MARK E. FERNALD, OF SAUGUSfMASSACH-USETTS.

SOLE-MARKING MACHINE.

Application filed' October a, 1915. Serial No'.'54z,871.

To all whom it may concern.

Be it known that I, MARK E. FERNALD, a citizen of the United States, residing at Sangus, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Sole-Marking Machines, of which the following is a specification.

The present invention relates to sole marking machines which are used in the manufacture of boots and shoes to mark the soles to be incorporated into shoes.

In the application for Letters Patent of the United States filed by me'April 19, 1915, Serial No. 22,312, I have described a sole nail or tack retainer which is inserted into the bottom of a last for the purpose of holding the sole nails'or tacks which secure the sole to the last bottom. The sole nail retainers are located at three separated points in the last bottom, namely, in the forepart, at the shank and in the heelseat.v In order to register the sole' on the bottom of the last the sole is first marked at the three places corresponding to the location of the three sole nail retainers on the bottom" of the last. The nails are then driven through the sole at the marked points and the projecting points of the nails are thenpresented to the sole nail retainers and driven firmly therein.

The object of the present'invention' is to provide a sole marking machine'which will mark the location of the sole nails on the sole. 3

To the accomplishment ofthis object and such others as may hereinafter appear the features of the invention relate to certain devices, combinations and arrangements of parts hereinafter described and then a set forth broadly and in detail inthe appended claims which possess advantages which will be apparent to those skilled in the art.

The various features ofthe present invention will be readily understood from an inspection of the accompanying drawings illustrating the best form of the invention at present known to the inventor, in which,

Figure 1 is a front elevatiompartly' in central longitudinal section, of the sole marking machine;

Fig. 2 is a plan;

Fig. 3 is a detail in side elevation, the shank marker'being shown turned back and into inoperative position; and

' Fig. 4 is a plan of 'a sole marked by the sole marking machine.

As shown in Fig. 4: the sole marking ma- ChlIlBPltCGS a mark 1 in the forepart, a mark 2 in the shank, and a mark 3 in the heelseat, of a sole 4. The sole is marked while supported on a fiat table 5 which is mounted at a convenient height upon legs 6.

The mark 1 is made by a prick-point 7 formed on the lower end of a rod 8 mounted to slide in a chamber 9. The point '7 is normally maintained retracted by a spring 10 which is coiled around the reduced shank of the rod 8 and interposed between the bot tom of the chamber 9 and a striking head 11 on the upper end of. therod. The little clrcle surrounding the marks (Fig. 1) is made by the peripheral edge of the lower end of the rodS-which is cut away to a comparatively sharp edge in the formation of the point 7. The chamber 9 is mounted onone end of an arm 12 which is pivoted on a V-shaped plate or gage 13 constructed to receive the toe end of the sole. The gage 13 is mounted to slide on the table 5. To this end the gage 13 is provided with slots 14 which embrace pins 15 (Fig. 1) loosely mounted on the table 5. The pins 15 are provided with enlarged heads 16 (Fig. 2) which frictionally engage the upper face of the gage 13 under the influence of springs 17 (Fig. 1) coiled around the pins 15 and interposed between the bottom of the table 5 andcollars 18 on the lower end of the pins 15.

The mark 3 is made by a prick-point 19 constructed and supported in a similar mannerto the prick-point 7. The point 19 is carried by an arm 20 which is pivoted on a V-shaped plate or gage 21 constructed to receive the heel end of the sole. The gage 21, like the gage 13, is mounted to slide on the table 5.

In order to slide the gages 13 and 21 in opposite directions to permit the introduction of a sole between them they are mount ed on blocks 20 and 20 which slide in ways formedin the table .5 The blocks 20 and 20 are provided, respectively, with depending arms 22 and 23 which pass through slots 24 and 25 in the table 5. The arm 22 is connected by a link 22 to one arm of a bell crank lever 26 which is pivoted on a horie 'zontal rod 27 carried by a frame 28 mounted intermediate the legs 6. The arm 23 is also connected by a link 23 to one arm of a bell crank lever 29 also pivoted on the rod 27 The lower arms of the bell crank levers 26 and 29 are connected to links 30 and 31 the lower ends of which are connected to a vertical rod 32 mounted to slide in lugs 33 formed on the frame 28. This connection between the bell cranklevers 26 and 29 forms a parallel motion device wherebythe gages 13 and 21 are moved uniformly in opposite directions. To actuate the bell crank levers to separate the gages the bell crank lever 29 is provided with a third arm 34 which is connected through a rod 35 to a treadle 36 pivoted at 36 on one of the legs'6 (Fig. 2). The gages 13 and 21 are separated through the manip ulation of the treadle 36 but are actuated in the opposite direction to embrace the opposite ends of a sole positioned between them by a' spring 37 one end of which is connected to the treadle 36 and the other end of which isconnected to the frame 28.

In order to tip the prick-points 7 and 19 out of the way of the operative in positionmg a sole between the gages 13 and 21 the arms 12 and 20 are provided, respectively, with depending pins 38 and 39 arranged to engage blocks 40 and 41, secured to thetable 5, during the separating movement of the gages, and thus tip the arms carrying the gitudinally on an arm 48 projecting from athe block 47 is pivoted.

points about their pivotal connections with the gages (dotted lines Fig. 1).

' The mark 2 is made'by a third prick-point 41*, similar in construction and mode of operation to the points 7 and 19, mounted on any arm 42 which is pivoted on a slide 43 mounted to slide transversely ina way 44 formed in the table 5. The location of the shank mark 2 is determined by a gage 45 constructed. toembrace the opposite edge of the shank of thesole (Figs. 1 and 2). The gage 45 comprises a pair of arms 46 pivoted on-a block 47 which is mounted to slide lon- To operate the machine the treadle 36 is first depressed against the tension of the spring 37 to separate the gages 13 and 21 and tip the points 7 and 19 into the dotted line position of Fig. 1. The sole is then placed on the table 5 with the shank thereof positioned between the arms 46 of the gage 45. The treadle is then released whereupon the spring 37 moves the gages 13 and 21 into engagement with the toe and heel ends of the sole. Owing to the ii-shaped formation of the toe and heel gages the sole is shifted on the-table until the gages bear uniformly on the ends of the sole. During this shifting movement of the sole the gage 45, owing to the clamping engagement of its arms 46 with the edges of the sole, to the pivotal movement of the hub 49 on the arm 23 and the sliding connection between theblock 47 and the arm 48, also shifts with the sole thereby properly positioning the shank markerIfor the style of sole operated upon. As shown in Fig. 2 the shank marker shifts transversely of the sole to accommodate the marker for right and left soles. Y

After the sole'has been positioned in the manner described the striking heads 11 of all the prick-points are struck with a hammer to project the points into the sole.

While the invention has been herein embodied in a sole marking machine for marking the location of the sole tacks on a sole it will be apparent to those skilled in the art that various features of the machine may be advantageously employed in marking soles for other purposes. v

It will be clear to'those skilled in this class of machines and with the general objects of the present invention in view that changes may be made in the details of'structure the described and illustrated embodiment thereof being intended as anexploitation of its underlying essentials the features whereof are definitely stated in their true scope in the claims hereto appended.
